[0026] Example 1

[0027] A polishing device for the inner pot of a rice cooker, such as Figures 1 to 3As shown, the system includes a cabinet 1, with a placement platform 3 fixed to the inner wall of the cabinet 1. Rotating rollers 4 are arranged in a circumferential array at the top of the placement platform 3. An electric telescopic rod 13 is installed at the center of the top of the placement platform 3. A support plate 14 is rotatably connected to the telescopic end of the electric telescopic rod 13. An electric telescopic rod 2 15 is fixed to the inner wall of the top of the cabinet 1. A fixing block 16 is connected to the telescopic end of the electric telescopic rod 2 15. A rotary motor 17 is installed on the inner wall of the fixing block 16. A pressure plate 18 is connected to the output end of the rotary motor 17. The pressure plate 18 is positioned opposite to the support plate 14. A lifting groove 5 is provided on one side of the inner wall of the cabinet 1. A clearance groove opposite to the lifting groove 5 is provided on one side of the placement platform 3. A lifting cylinder is provided at the bottom of the lifting groove 5. Two adjusting blocks 6 are slidably fitted on the inner wall of the lifting groove 5. Two threaded rods 8 are rotatably connected to the inner wall. The threaded rods 8 are threadedly engaged with one adjusting block 6 and slidably engaged with the other adjusting block 6. A moving motor that drives the threaded rods 8 to rotate is provided on one side of the lifting groove 5. A grinding roller 7 is rotatably connected to the top of the adjusting block 6. The two grinding rollers 7 are arranged in parallel. A grinding motor that drives the rotating roller 4 to rotate is installed inside the adjusting block 6. A collecting head 9 is provided on one side of the placement platform 3. A collecting cavity 10 is provided at the bottom of the cabinet body 1. The bottom of the collecting head 9 is connected to the collecting cavity 10. An exhaust fan 12 is provided on one side of the collecting cavity 10. A filter plate 11 is provided between the connecting port of the collecting cavity 10 and the collecting head 9 and the exhaust fan 12. The filter plate 11 has an inclined surface on the side away from the exhaust fan 12. A cabinet door 2 is hinged to one side of the cabinet body 1. An observation window is provided on the outer wall of the cabinet door 2.

[0028] During polishing, open cabinet door 2, move motor to drive threaded rod 8 to rotate, causing adjusting block 6 to move inside lifting groove 5, changing the position of two polishing rollers 7, placing the inner liner above placement table 3, with the outer wall of the inner liner positioned between the two polishing rollers 7. Electric telescopic rod 15 and electric telescopic rod 13 push support plate 14 and clamping plate 18 to move relative to each other, clamping and fixing the inner liner. Rotary motor 17 drives clamping plate 18 to rotate, and the friction between clamping plate 18 and the inner liner causes the inner liner to rotate. Rotating roller 4 keeps the inner liner and placement table 3 apart. The sliding friction is transformed into rolling friction, reducing the rotational friction of the inner liner. At the same time, the grinding motor drives the grinding roller 7 to rotate, simultaneously grinding the inner and outer surfaces of the inner liner. The exhaust fan 12 draws the air out of the collection chamber 10 to form a negative pressure, and the waste generated by grinding is sucked into the collection chamber 10 through the collection head 9. The filter plate 11 blocks the waste, causing it to accumulate in the collection chamber 10. During the grinding process, the lifting cylinder can drive the grinding roller 7 to rise and fall, changing the height of the grinding roller 7 so that the grinding roller 7 can grind the inner liner at different heights.

[0029] By incorporating an adjusting block 6 and a grinding roller 7, the two surfaces of the inner liner can be ground simultaneously, improving grinding efficiency.

[0030] The inner liner is fixed by means of an electric telescopic rod 13, a support plate 14, an electric telescopic rod 2 15, a fixing block 16, a rotary motor 17, and a pressure plate 18. Compared with clamping the side of the inner liner by means of a clamping rod, it does not affect the grinding of the side of the inner liner and reduces the dead corners of grinding.

[0031] Example 2

[0032] A polishing device for the inner pot of a rice cooker. This embodiment is based on embodiment 1 and makes the following improvements, such as... Figure 3 , Figure 4 As shown, a jet pipe 20 is provided on one side of the grinding roller 7, and two jet pipes 20 have opposite air blowing ports on their side walls. An air supply pipe 19 is provided on one side of the exhaust fan 12, and the other end of the air supply pipe 19 is connected to the two jet pipes 20.

[0033] During the polishing process, the airflow drawn from the collection chamber 10 by the exhaust fan 12 is input into the jet pipe 20 through the air supply pipe 19. The airflow blows from the jet pipe 20 onto the polished inner liner surface, blowing off the waste debris adhering to the inner liner surface after polishing, thus reducing the need for cleaning the inner liner after polishing.

[0034] By incorporating an air supply pipe 19 and an air jet pipe 20, the surface of the inner liner is blown away during the polishing process, removing the debris adhering to the surface of the inner liner after polishing and reducing the need for cleaning the inner liner after polishing.

[0035] Working principle: During polishing, the cabinet door 2 is opened, and the moving motor drives the threaded rod 8 to rotate, causing the adjusting block 6 to move inside the lifting groove 5, changing the position of the two polishing rollers 7. The inner liner is then placed above the placement table 3, with the outer wall of the inner liner positioned between the two polishing rollers 7. The electric telescopic rod 15 and the electric telescopic rod 13 push the support plate 14 and the clamping plate 18 to move relative to each other, clamping and fixing the inner liner. The rotating motor 17 drives the clamping plate 18 to rotate, and the friction between the clamping plate 18 and the inner liner causes the inner liner to rotate. The rotating roller 4 converts the sliding friction between the inner liner and the placement table 3 into rolling friction, reducing the rotational friction of the inner liner. At the same time, the polishing motor drives the polishing rollers 7 to rotate. The grinding roller 7 rotates, simultaneously grinding both the inner and outer surfaces of the inner liner. The exhaust fan 12 draws air out of the collection chamber 10 to create negative pressure, and the waste generated during grinding is sucked into the collection chamber 10 through the collection head 9. The filter plate 11 blocks the waste, causing it to accumulate in the collection chamber 10. The airflow enters the jet pipe 20 through the air supply pipe 19, and the airflow blows from the jet pipe 20 onto the surface of the inner liner after grinding, blowing off the waste adhering to the surface of the inner liner after grinding, reducing the need for cleaning the inner liner after grinding. During the grinding process, the lifting cylinder can drive the grinding roller 7 to rise and fall, changing the height of the grinding roller 7, so that the grinding roller 7 can grind the inner liner at different heights.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
